Varnish is a web accelerator tool, which has been gaining a lot in popularity in recent years, as it can increase the load speed of any site, sometimes even by one hundred percent, based on the content. This tool is sometimes referred to as a caching HTTP reverse proxy too and is used to reduce the overall load on the server and to enhance the browsing speed for the site visitors. Anytime a visitor loads a page on a given website, the browser request is handled by the web server and the requested content is returned as a reply. If the Varnish accelerator is enabled, it caches the pages that the visitor opens and if any of them is loaded again, it is served by Varnish and not by the web server directly. The improvement in the overall performance is due to the fact that the accelerator processes the browser requests significantly faster than any web server, which results in much faster browsing speeds for the visitors. If any data is modified in the meantime, the cached pages will also be updated the next time somebody attempts to open them.
Varnish in Shared Hosting
If you host your sites in a shared hosting account with us, you’ll be able to activate Varnish with several mouse clicks through your Control Panel. The platform comes as an upgrade with all our shared hosting plans and you can choose how many websites will use it and the maximum amount of system memory that will be used for the cached content. The two upgradeable features in the Upgrades section of the Control Panel are the amount of memory and the number of instances and they aren’t linked directly to each other, so you can choose if you need lots of memory for a single large-sized site or less memory for multiple smaller ones. You can unleash the full potential of Varnish in case the sites use a dedicated IP. Using the hosting Control Panel, you can easily start/restart/disable an instance, clear the cached data independently for each website that uses Varnish or see an in-depth log file.
Varnish in Semi-dedicated Servers
Varnish is included in the basic service set that you’ll acquire when you decide to host your sites in a semi-dedicated server account. You can set it up for any of your websites through our leading-edge Hepsia hosting Control Panel. The default amount of memory that Varnish can use to cache content is 64 MB, but if you decide that you want more, you can upgrade this amount of memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the websites that can use this platform simultaneously. As these two things aren’t tied to each other, you can use a few Internet sites with the default memory or you can add more memory in increments of 32 megabytes and use all of it for one single site. Varnish performs best when you use a dedicated IP address for the sites that utilize its power. Hepsia will offer you an easy way of restarting any instance. Also, you’ll be able to clear the cached content with only one single mouse click.
Varnish in VPS Servers
You can take advantage of Varnish with all our VPS server packages at no additional fee, as the platform is pre-installed and is included by default. The only prerequisite is that the VPS must come with the Hepsia hosting Control Panel, through which you will be able to set up Varnish for any of your sites with only a few clicks. Each package offers a different amount of memory for content caching purposes, but you’ll get minimum several hundred MB, which is sufficient enough even for multiple popular sites. Soon after you activate the Varnish platform, it will begin caching the content that your website visitors access, so you will notice the significantly better site load speeds and the less load on the VPS very soon. Varnish will permit you to use a less expensive VPS, as you won’t need that many resources to sustain the uninterrupted operation of your sites even if you’ve got resource-hungry Internet sites with plenty of visitors. Optimal results are achieved if the Internet sites that use the Varnish caching platform also use a dedicated IP address.
Varnish in Dedicated Servers
In case you order a dedicated server with the Hepsia Control Panel, you will get the Varnish content caching platform at no extra charge and you’ll have complete control over it via an extremely easy-to-work-with GUI – you will be able to start, to delete or to restart an instance, to view a detailed system log, to clear the cache associated with any website and much, much more. The Varnish caching platform will have several GB of system memory at its disposal, so even if you host resource-intensive Internet sites with an immense number of visitors, you will notice the considerably better page loading speeds and the less server load. This will become a fact soon after you begin using the Varnish platform, as it will need a certain amount of time to cache the content that visitors browse. You can take full advantage of the platform’s potential if the websites that are using it use also a dedicated IP address, but considering the fact that your dedicated server comes with a few IPs by default, you won’t need to pay anything on top of the monthly charge for the server itself.
